This rear oxygen sensor is designed for Chang’an Lingxuan (2017–2019 1.5T/1.6L) and Changan Oushang (2016–2019 1.5L/1.6L), also compatible with some other platforms on the same family. Core function: real-time monitoring of oxygen content in exhaust and feeding signals to the ECU to precisely control the air–fuel ratio, ensuring engine efficiency and emission compliance. OEM 28510129 (factory counterpart 28493151) for quick compatibility checks in stock systems. Replacement difficulty: medium; use a dedicated oxygen sensor socket; avoid pulling wires; after installation, clear fault codes with a diagnostic tool. The upgraded aftermarket version improves sensor response and heat resistance, effectively reducing idle instability or fuel economy deterioration due to aging; suitable as an economical substitute for OEM parts.
